Maybe I'm being overly anal.. but I think there should be a little protocol before starting up a challenge... clubs no -- those can be for anyone.. but challenges there should be a protocol...
and if it means running it by a committee of their peers, then I'm Ok with that... if the challenge is a good idea it will get approved, if it's not a good idea, it's doubtful that people would have signed up for it anyhow.
I think its a way of acting like a traffic cop... to make sure that there's always at least one challenge runnig at a time. and we're not inundated with challenges
Idon't even have to be on the committe.. but maybe 3 - 5 people who regularly participate in the challenges could be nominated to serve on the committe for XX amountof time.. and after that time is up - new committe members are appointed so that everyone who wants a chance cang et a chance
